iPhone

When plug my iPhone into the USB input, it shows that it's searching for the device but then I get an error message saying something like "this device isn't supported". I am able to charge the phone via the USB, but can't play audio or control it with the infotainment system. I have an iPhone 4S (haven't yet upgraded to ios 6). Any ideas?

Re: iPhone

Are you using the adapter that came with the car?
It's a weird connector with split USB and straight jack that attaches to the car end.
If you look closely next to the USB port in the center console, there's a second hole for the additional jack.
If you're just using a simple USB cord that came with your phone, you will not get any audio.

Has No Left, please let me know if you're still having concerns after investigating shchow's cord suggestions. I'm reachable via email (Katie_Lucille@gmexpert.com) and am happy to investigate if you continue to have frustrations.

I have an iPhone 4 and was curious to see if it would work with the special cord. The car's iPhone cord connection wouldn't physically fit all the way into the bottom of the iPhone, so the system didn't recognize it. Normally, I keep an older iPod Nano hooked up and it works fine. Anyone else have this problem?

I have an iPhone 3 and I am using my adapter cord that came with the CTS when i bought the car brand new. I have had my navigation replaced at a Cadillac dealer and now when I plug in my phone I get this message "this usb is not supported. Disconnect the device." This was my 3rd navigation system and the two times before this it worked fine. I took it back to the dealer and they said that all the setting are correct but it still won't work. I can hear the music and my phone will charge but I can't see the playlist or control the music with the car controls anymore. Anyone have this issue?

Re: iPhone

USB ports are not all the same. I think USB is on 2.5 or something. In some cases they are not back compatible. iPhone 3 uses an older USB standard (1.0 ?) and if you got a new Nav unit, it may have the new USB port that electrically can't talk to the phone. My friends older computer would not talk to his new iPhone 4 just for that reason. Go get a new phone.
